>>Is it IHOB now?<<
You haven’t seen the commercial? It is sung to “Happy Birthday to You” and they emphasize the IhoPPPPPP — the lyric says the “B” was just a marketing gimmick.
Very funny and IMHO very successful.
No I have not seen the commercial but when the “IHOB” came out I speculated that it was probably a marketing ploy. Worked well as IHOP got a lot of free publicity.
